This is meant for spirits, and will not give you a proper gravity reading for beer. I would go with the triple scale http://www.northernbrewer.com/beer-and-wine-triple-scale-hydrometer I hope that this helps!

No, it cannot. Hydrometers don't actually measure alcohol directly, rather they measure the gravity or density of a liquid. In this case, the density corresponds to the sugar content; and you compare the pre-fermentation gravity to the post-fermentation gravity to see how much sugar was converted into alcohol.
